awk idea
Hello everybody,

I am new here as well as in scripting.
I need some help. I have log files that are boring to examine. I wanted to use awk to do this:

-get the lines that match the eight field (user mac address)
-now sort them according to date (first 2 fields)
-print the following:

"number of repetition" "Date" "my text about user "

I started with this:
Code:
awk '{if ($8~"user mac address") printf("my text\n")}' log_file

and i got my text for eg. 5 times because this users mac appears 5 times in log:
Code:
my text
my text
my text
my text
my text

what is the best way to get this:
Code:
3 Jun 17 my text 
2 Jun 16 my text

thanx in advance

maybe you want to use an array i.e a[yourMacAddr]="value you want"
or you paste an example including input and outputs.

@sk1418, thanx for replying.

this is the shorten example of log lines:
Code:
Jun 16 07:12:11 dhcpd: DHCPDISCOVER from "usermac1"
Jun 16 09:42:22 dhcpd: DHCPDISCOVER from "usermac1"
Jun 16 11:45:55 dhcpd: DHCPDISCOVER from "usermac1"
 
Jun 17 08:47:29 dhcpd: DHCPDISCOVER from "usermac2"
Jun 17 10:49:11 dhcpd: DHCPDISCOVER from "usermac2"
Jun 17 12:38:15 dhcpd: DHCPDISCOVER from "usermac1"

i want the output to look like this :
Code:
Jun 16 user1 3
Jun 17 user2 2
Jun 17 user1 1

p.s. I dont have much users so i could corelate their mac addresses with names

Code:
% cat testfile
Jun 16 07:12:11 dhcpd: DHCPDISCOVER from "usermac1"
Jun 16 09:42:22 dhcpd: DHCPDISCOVER from "usermac1"
Jun 16 11:45:55 dhcpd: DHCPDISCOVER from "usermac1"
 
Jun 17 08:47:29 dhcpd: DHCPDISCOVER from "usermac2"
Jun 17 10:49:11 dhcpd: DHCPDISCOVER from "usermac2"
Jun 17 12:38:15 dhcpd: DHCPDISCOVER from "usermac1"

% cat testfile | awk '{print $1, $2,  $NF}' | sort -u
   
Jun 16 "usermac1"
Jun 17 "usermac1"
Jun 17 "usermac2"

Better
Code:
% cat testfile | awk '/[^ ]/ {print $1, $2, $NF}' | sort | uniq -c
      3 Jun 16 "usermac1"
      1 Jun 17 "usermac1"
      2 Jun 17 "usermac2"

Ok, the best Smilie (not, of course)
Code:
% cat testfile | awk '/[^ ]/ {print $1, $2, $NF}' | sort | uniq -c | perl -lane 'print "@F[1..$#F] $F[0]"'
Jun 16 "usermac1" 3
Jun 17 "usermac1" 1
Jun 17 "usermac2" 2
